################################################################################ # WL#6833: GCS Replication: Read-set free Certification # Module (DBSM Snapshot Isolation) # # Scenario 3: Replay a binary log into a group # # Verify Group Replication behavior when we replay a binary # log to a group. # # Test: # 0. The test requires three servers: M1, M2 and M3. # 1. Execute some transactions on M3, which doesn't belong to the group. # 2. Setup Group Replication on M1 and M2. # 3. Replay M3 binary log into group (M2). # 4. Validate data on M3. # 5. GTID_EXECUTED on M1 must contain GTID_EXECUTED from M3. Validate data on M1. # 6. GTID_EXECUTED on M2 must contain GTID_EXECUTED from M3. Validate data on M2. # 7. Stop and start Group Replication on M1 to validate that recovery is working # working properly. # 8. Clean up. # 9. Stop Group Replication on M1 and M2. ################################################################################ --let $group_replication_group_name= 8a94f357-aab4-11df-86ab-c80aa9420001 --source ../inc/have_group_replication_plugin.inc --let $rpl_skip_group_replication_start= 1 --let $rpl_server_count= 3 --source ../inc/group_replication.inc --echo --echo ############################################################ --echo # 1.
